Title: | Finite-element modeling of intermediate crack debonding in FRP-plated RC beams | Authors: | Chen, GM Teng, JG Chen, JF |
Issue Date: | Jun-2011 | Source: | Journal of composites for construction, June 2011, v. 15, no. 3, p. 339-353 | Abstract: | Intermediate crack-induced debonding (IC debonding) is a common failure mode of RC beams strengthened with externally bonded fiber-reinforced polymer (FRP) reinforcement. Although extensive research has been carried out on IC debonding, much work is still needed to develop a better understanding of the failure mode and a more reliable strength model. This paper presents an advanced finite-element (FE) model on the basis of the smeared-crack approach for predicting IC debonding failure. Existing FE models of the same type are generally deficient in capturing localized cracks (both their pattern and widths). This deficiency is overcome in the proposed FE model through the accurate modeling of interfaces between the concrete and both the internal steel and the external FRP reinforcements. The capability and accuracy of the proposed model are demonstrated through comparisons of its predictions with selected test results. The importance of accurate modeling of localized cracking is also explained using numerical results obtained from the FE model. | Keywords: | Fiber-reinforced polymer Reinforced concrete Concrete beams Cracking Bonding Interfaces Shear stress Strain distribution Flexural strength Finite-element method |
